This invention relates to certain new and useful improvements in barrels and refers more particularly to metal beer barrels.

Barrels of this type comprise an inner container within an outer shell spaced from the inner container to afford insulation. Heretolfore, these two component parts of the barrel have been permanently connected by welding which made it extremely diicult to open the barrel for the purpose of repairing leaks.

To avoid this diiculty, this invention has as one of its objects to provide a barrel in which the inner and outer shells are readily detachably connected.

Another objectionable feature of past barrel constructions is the necessity for driving the bung in place. This had a tendency to loosen the pitch from the inner walls of the barrel. 'Ihe present invention overcomes this objection by -0 the provision of a threaded cap or closure for the bung opening. Y In this connection, it is an object of this invention to provide a construction at the bung opening, whereby the application of the closure plug or cap affords a tight readily releasable connection between the inner container and the outer shell.

With a View toward facilitating opening of the barrel for purposes of repair, and also to provide a cushioned or shock absorbing suspension for the inner container, this invention contemplates as another object the provision of removable wooden heads for the barrel, which engage the inner container to firmly hold the same against shifting with respect to the shell. Y

A further object of this invention resides in the provision of novel means for removably securing the wooden heads in place.

With the above and other objects in view, which will appear as the description proceeds, my invention resides in the novel construction, co-mbination, Vand arrangement of parts substantially as hereinafter described and more particularly deiined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come Within the scope of the claims.

In the accompanying drawings,A I have illustrated two complete examples of the physical 50 embodiment of my invention constructed according to the best modes I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a perspective view of a barrel embodying' this invention, parts thereof being broken away and in section;

Figure 2 isa perspective view partly in section showing a modified embodiment of the invention; and

Figure 3 is a view similar to Figure 2, illustrating another modification of the invention.

Referring now more particularly to the accompanying drawings in which like numerals indicate like parts throughout the several views, the numeral 5 designates the inner container of the barrel and the numeral 6, the outer shell. The inner container is of conventional construction and consists oi tWo end to end cup-shaped sections welded together as at 'I.

The conventional practice both in wood barrels and in metal barrels is to line the interior With pitch. This requirement may be obviated by making the inner container of aluminum which, with the present construction, is entirely easable as the outer shell is so constructed as to afford adequate protection for an aluminum inner container.

One end of the inner container has a tap ntting 8 secured thereto, through which the contents of the barrel are withdrawn in the conventional manner, and the side of the container is provided with the usual bung opening. Adjacent the opening, the inner container is pressed out to accommodate Yan internally threaded anged collar 9 which is secured thereto. It is noted that the outer end of the collar is flush With the adjacent outer wall of the bulged container portion. This permits a close t between the container and the shell at the bung opening Without interfering with the free removal of the container from the shell.

The outer shell 6 consists essentially of a cylinder of sheet steel provided with annular reinforcing beads I3 encircling the medial portion of the barrel and smaller inwardly directed beads II near the ends of the barrel. The dia-meter of the outer shell is large enough to leave a substantial space between it and the inner container to afford an insulating space. This space may be left open or filled with a suitable insulating medium.

Closing the ends of the shell are wooden heads I2. These heads lit snugly within the shell and are provided with annular rounded flanges I'I', which extend into the space between the container and the shell, contacting the peripheral edges of the container and the adjacent walls of the beads I I. The wooden heads thus hold the inner container against shifting with respect to the shell.

The wooden heads are removably secured in position by angle iron hoops I3 encircling the outer edge portion of the heads with their upstanding flanges I4 engaging the adjacent inner wall of the outer shell.l The lateral iianges I5 of the hoops are preferably nested in annular recesses I6 in the heads, and the upstanding flanges which may be curled inwardly as at II, are engaged under inwardly directed flanges I8 To preclude the possibility of water leaking,vv into' the insulating space at the tap 8, the outer end of the tap has a ring nut I9 threaded thereon, 1

The nut I9 is received in a suitable groove cut into the wooden head and upon being-"drawnl -v tight, clamps the adjacentV portion of the headp against the end wall of the innerfcontainer to provide a fluid-tight connection. v Y Y Opposite the bung opening ofthe inner Vcontainer, the outer shell is depressedand apertured `as at 2D to accommodate a closure plug.2I which is threaded into the collar 9. The plug 2| has an enlarged head -provided `with* a hexagonal socket. Between the enlargedv head and the adjacent wall of the outer shell, a packing washer 22 is disposed. The washer 22 may be'of lead or any other suitable materialand aordsfa fluidtight seal upon tightening of the plug.r In'this manner, the bung opening is closedv inV a convenient manner without necessitating objectionable pounding and the inner container and outer shell are securely locked together. Y l 1 The inner container may be further secured to theouter shell adjacent the bung opening by a plurality of screws 22', passed through countersunk openings in the outer shell and threaded in tapped holes in the inner shell and flange of the collar 9. The screws 22, thus holdr the inner container and outer shell iirmly together when the plug 2! is removed to preventwater from entering the space between the inner container andouter shell during washing ofthe barrel-.1 Y, In the event water does accumulate within .the

`space 4between the inner container'and `outer shell, it may bedrained by removing afdrain plug 3!) located at the bottom ofthe barrel.;`

v 'Iheremovable woodenV heads f I2 not only make a it possible to conveniently remove the inner container, but also provide a cushioned shock absorbing suspension for the inner container. Also, by virtue of the degree of resilience, kwhich wood has, it is possible to more rigidly` secure the inner container against movement within the outer shell, as during the application .ofl the wooden heads, they may be slightlycompressed., n;

Y It is, of course, understood that while the use ofrwood for the heads is preferable, other niaterials which have characteristics similar to; that of wood, may be employed without deviating from the spirit of the invention. f f

If desired, the hoops at the ends of the barrel may be formed in two half sections 23,l asA illustrated in Figure 2. By dividingthehoops into two separate sections, removal of the inner con,-

tainer is facilitated as it is only 4necessary to curl back a portion of the flangeatfthe end of the outershell. '.Ihe wooden head may be destroyed to further facilitate the removal of.the hoopsections 23. If desired, the hoop sections 23 maybe secured to the heads byscrewsgZII.Y I

The removal of the hoops mayfbefurther facilitated by splittingthem at one pointfasat 2 5 in Figure 3, and cutting back the adjacent ends ofthe lateral ilanges I5 to leave aspace26. In this construction, the flange I8 of the outer shell .extends down over theadjacentedg'e of the hoop Vpanded position.

only a slight distance so that upon the application of a contracting force on the hoop by means of a suitable tool engaging studs 27 carried by the ends of the flange I5, the hoop may be sprung past the small ledge on the flange YIIS. The annular 'recess I6 in the wooden headtogether Vwith the rim on the-flange I 8 normally holds ,the hoop in its expanded active position, but upon the application of sucient contracting g-force, the hoop may be sprung past these ledges as will be readily apparent.

With the'construction in Figure 3, it is necessary to destroy the wooden head after the hoop las'beenv removed to permit complete disassem- From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art, that this invention affords a novel construction for barrels and particularly beer barrels.
